Android Activity Force Schließen Problem

Question

enter code here Ich versuche, einen Fortschritt Dialog in meiner Android-Anwendung zu setzen, und ich habe ein wenig Probleme damit. Ich bin neu in Android und folge diesem Tutorial:

Wenn ich meine App auf meinem Handy teste alles ist es Force Closes. Kann jemand bitte helfen? Heres meine .Java Aktivität:

public class XXXXXActivity extends Activity { 
private ProgressDialog progressDialog; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    WebView myWebView=(WebView)findViewById(R.id.webview); 
    myWebView.addJavascriptInterface(new JavaScriptInterface(this),"Android"); 
    WebSettings websettings = 
      myWebView.getSettings(); 
    websettings.setJavaScriptEnabled(true); 
    myWebView.setWebViewClient(new MyWebViewClient()); 
    myWebView.loadUrl("http://XXXXX.com"); 
} 

private void runDialog(final int seconds) 
{ 
    progressDialog = ProgressDialog.show(this, "Please wait...", "Loading..."); 
    new Thread(new Runnable(){ 
     public void run(){ 
      try { 
         Thread.sleep(seconds * 1000); 
       progressDialog.dismiss(); 
      } catch (InterruptedException e) { 
       e.printStackTrace(); 
      } 
     } 
    }).start(); 
} 
public class JavaScriptInterface { 
    Context mContext; 
    /** Instantiate the interface and set the context*/ 
    JavaScriptInterface(Context c) { 
     mContext = c; 
    } 
    /** Show a toast from the web page*/ 
    public void showToast(String toast) { 
     Toast.makeText(mContext, toast, Toast.LENGTH_SHORT).show(); 
    } 
} 
private class MyWebViewClient extends WebViewClient { 
    @Override 
    public boolean shouldOverrideUrlLoading (WebView view, String url) { 
     view.loadUrl(url); 
     if 
     (Uri.parse(url).getHost().equals("XXXXX.com")) { 
      // This is my web site, so do not override; let my WebView load the page 
      return false; 
     } 
     // Otherwise, the link is not for a page on my site, so launch another Activity that handles URLs 
     Intent intent=new 
       Intent (Intent.ACTION_VIEW,Uri.parse(url)); 
     startActivity(intent); 
     return true; 
    } 
}

Ich sehe ein Problem: Sie Dialog in Nicht-GUI-Thread entlassen:

new Thread(new Runnable(){ 
     public void run(){ 
      try { 
         Thread.sleep(seconds * 1000); 
       progressDialog.dismiss(); 
      } catch (InterruptedException e) { 
       e.printStackTrace(); 
      } 
     } 
    }).start(); 

Dieser Code ist sehr seltsam Ich denke, du solltest die Logik überhaupt neu schreiben.
